AI Technical Summary
In existing milk tea paper-plastic cup filters, the filter cartridge moves up and down, causing milk tea liquid to enter the gaps and stagnate, posing a food safety hazard.
A positioning ring with an inverted L-shaped axial cross section is formed on the outer wall of the filter cartridge to form an annular groove to avoid the milk tea liquid. The connection between the connecting sleeve and the filter cartridge is ensured by the limiting structure and adhesive bonding to prevent separation.
It effectively prevents milk tea liquid from entering the gaps, eliminates the accumulation of dirt and grime, ensures food safety, and improves the user experience.

Abstract
Claims
1. An improved milk tea paper-plastic cup filter, comprising a filter cylinder (1) in the shape of a long barrel and a connecting sleeve (2) sleeved on the outer end of the filter cylinder (1), one side of the connecting sleeve (2) being provided with an L-shaped handle (3), the handle (3) comprising a connecting portion (3a) arranged horizontally and used for connecting with the outer wall of the connecting sleeve (2), characterized in that, The upper end of the filter cylinder (1) is bent outward to form a ring (1a) coaxial with the filter cylinder (1). The axial cross section of the ring (1a) is inverted L-shaped. The ring (1a) is composed of a positioning ring (1a1) and a connecting ring (1a2) that are perpendicular to each other. The connecting ring (1a2) is located between the positioning ring (1a1) and the filter cylinder (1). The shape and size of the inner hole of the positioning ring (1a1) are matched with the outer wall of the connecting sleeve (2). The connecting sleeve (2) is inserted into the positioning ring (1a1) and pressed against the connecting ring (1a2). An opening (1a3) is provided on one side of the positioning ring (1a1) for the connecting part (3a) to extend into.
2. The improved filter for milk tea paper plastic cup according to claim 1, characterized in that, The positioning ring (1a1) and the connecting sleeve (2) are further provided with a limiting structure for the upward movement of the limiting ring body (1a).
3. The improved milk tea paper cup filter of claim 2, wherein, Both the connecting sleeve (2) and the filter cartridge (1) are elastic. The limiting structure includes a ring of protrusions (1a5) formed on the inner wall of the positioning ring (1a1). The outer wall of the connecting sleeve (2) is provided with a notch that matches the protrusions (1a5). The number of notches and protrusions (1a5) is the same, and each protrusion (1a5) is inserted into the corresponding notch.
4. The improved milk tea paper cup filter of claim 3, wherein, The outer wall of the positioning ring (1a1) is recessed inward to form the aforementioned protrusion (1a5) on the inner wall of the positioning ring (1a1).
5. The improved milk tea paper cup filter of claim 2, wherein, A conical guide surface (1a4) is formed on the lower inner wall of the positioning ring (1a1). The guide surface (1a4) and the positioning ring (1a1) are coaxially arranged. The diameter of the guide surface (1a4) gradually increases from top to bottom, and the lower end of the guide surface (1a4) extends to the bottom surface of the positioning ring (1a1).
6. The improved milk tea paper cup filter of claim 5, wherein, An annular mounting groove is formed between the inlet surface (1a4) and the connecting sleeve (2), and the mounting groove is coaxially arranged with the connecting sleeve (2). The aforementioned limiting structure is glue filled in the mounting groove.
7. The improved milk tea paper cup filter of claim 3, wherein, The filter cartridge (1) is made of stainless steel; the connecting sleeve (2) is made of plastic.
